Panasonic offers Ultra Low Power, Bluetooth Low Energy Module through TTI, Inc. The PAN1721 is a cost-effective, ultra low-power, system-on-chip (SoC) for Bluetooth Low Energy applications. The module includes an eight channel, twelve bit analog-to-digital converter, 19 GPIOs plus battery and temperature sensors. A single device for both BLE master or slave nodes. The PAN1721 combines an excellent RF transceiver with a high performance low power 8051 microcontroller, in-system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals.
The PAN1721 is an ideal choice for applications where battery life is a critical application requirement, using only 500 nA in sleep mode. Short transition times between operating modes–3 uS Wake-Up – and power efficient hardware further reduce current consumption.
